In an interesting development in cloning, a cloned cow in Japan gave birth naturally to a healthy calf. The researchers responsible for Dolly the sheep managed to get her to give birth, but this appears to be the first confirmed incident of a cloned cow giving birth.
“There have been arguments over the fertility of cloned cattle but the birth can be seen as a convincing answer,” Koichi Yamamoto, deputy director of the Ishikawa Prefectural Livestock Research Center where the cow gave birth, told the BBC. “Kaga No 2 is feeding its calf and it shows that cloned cows can recognise their own babies and may have maternal instincts.”
